Description

Patent application

Monitoring of loading and / or unloading of dishwashers

area

Exemplary embodiments relate to a method for a dishwasher and a device for use in a dishwasher, in particular for monitoring loading and / or unloading of dishwashers.

background

Methods for operating or controlling dishwashers are known from the prior art. The aim of operating such dishwashers is typically to be extremely user-friendly and at the same time to achieve the best possible result (in the case of a

Dishwasher to achieve a particularly flawless cleaning result).

One approach to achieve a high level of user friendliness would be, for example

Optimizing the user interface (input devices, output devices). If, for example, increased contamination is to be taken into account, the user must take this into account manually, for example, and select an appropriate program. Approaches are also conceivable in which device parameters are automatically adjusted in order to achieve the best possible result. In this case, for example, parameters internal to the dishwasher are adapted to one another, such as, for example in the case of a dishwasher, the program carried out by the dishwasher, for example to the amount of objects to be cleaned, with which the

Dishwasher is loaded. This already enables an improvement in the result, but the user must actively select the appropriate program.

However, it is disadvantageous that both the user-friendliness that can be achieved in this way and the result that is achieved in this way continue to be in need of improvement in many situations and scenarios.

General description of some exemplary embodiments of the invention

Against this background, the object of the invention is to improve the result to be achieved with the dishwasher with the greatest possible ease of use.

A wireless communication interface is, for example, a communication interface according to a wireless communication technology. An example of a wireless

Communication technology is a local radio network technology such as Radio Frequency Identification (RFID) and / or Near Field Communication (NFC) and / or Bluetooth (e.g. Bluetooth Version 2.1 and / or 4.0) and / or Wireless Local Area Network (WLAN). RFID and NFC are specified, for example, in accordance with ISO standards 18000, 1 1784/1 1785 and ISO / IEC standard 14443-A and 15693. For example, WLAN is specified in the standards of the IEEE 802.1 1 family. Another example of a wireless communication technology is a local radio network technology such as a mobile radio technology, for example Global System for Mobile Communications (GSM) and / or Universal Mobile Telecommunications System (UMTS) and / or Long Term Evolution (LTE). The GSM, UMTS and LTE specifications are maintained and developed by the 3rd Generation Partnership Project (3GPP).

A wired communication interface is, for example

Communication interface according to a wired communication technology. Examples of a wired communication technology are a local area network (LAN) and / or a bus system, for example a controller area network bus (CAN bus) and / or a universal serial bus (USB). For example, CAN bus is specified in accordance with ISO standard ISO 1 1898. For example, LAN is specified in the standards of the IEEE 802.3 family. It goes without saying that the output module and / or the sensor module can also comprise other means not listed.

According to the second aspect of the invention, an alternative device is also described, comprising at least one processor and at least one memory with computer program code, the at least one memory and the computer program code being set up to carry out at least one method according to the first aspect with the at least one processor and / or to control. Under a processor, for example, a control unit, a microprocessor, a microcontrol unit such as a microcontroller, a digital signal processor (DSP), should

Examples of a data processing system are a computer, a desktop computer, a server, a thin client and / or a portable computer (mobile device), such as a laptop computer, a tablet computer, a wearable, a personal digital assistant or a smartphone ,

Individual method steps of the method according to the first aspect can be carried out here with a sensor device which also has at least one sensor element or sensor (s). Likewise, individual method steps, which, for example, do not necessarily have to be carried out with the sensor device, can be carried out by a further device be carried out, which is connected in particular via a communication system to the device, which has at least one sensor element or sensor (s).

Further devices can be provided, for example a server and / or for example a part or a component of a so-called computer cloud, which

Computing resources dynamically for different users in one

Provides communication system. In particular, a computer cloud is one

Data processing infrastructure understood according to the definition of the "National Institute for Standards and Technology" (NIST) for the English term "cloud computing". An example of a computer cloud is a Microsoft Windows Azure Platform.

According to the second aspect of the invention, a computer program is also described which comprises program instructions which cause a processor to execute and / or control a method according to the first aspect when the computer program runs on the processor. An exemplary program according to the invention can be stored in or on a computer-readable storage medium which contains one or more programs.

According to the second aspect of the invention, a computer-readable storage medium is also described which contains a computer program according to the second aspect. On

computer readable storage medium can e.g. be designed as a magnetic, electrical, electro-magnetic, optical and / or other storage medium. Such a computer-readable storage medium is preferably objective (that is, “touchable”), for example it is as

Data carrier device formed. Such a data carrier device is, for example, portable or permanently installed in a device. Examples of such a data carrier device are volatile or non-volatile random access memories (RAM) such as e.g. NOR flash memory or with sequential access such as NAND flash memory and / or memory with read-only access (ROM) or read-write access. Computer readable, for example, should be understood to mean that

Storage medium can be read and / or written by a computer or a data processing system, for example by a processor.

According to a third aspect of the invention, a system is also described, comprising one or more devices which together carry out a method according to the first aspect.

In the following, exemplary features and exemplary configurations are described in more detail according to all aspects:

The course of measured acceleration values is, for example, of a plurality of measured acceleration values that were recorded over a predetermined period of time. represents, wherein the respective absolute measured acceleration values are represented to represent the course over a time axis.

The dishwasher usually uses a cleaning agent (e.g. so-called

Dishwasher tablets and / or rinse aid) for cleaning objects brought into the treatment room, such as. B. cutlery, dishes, pans or pots, to name just a few non-limiting examples.

According to an embodiment of the method according to the first aspect, the at least one device performing the method comprises the dishwasher and / or a device separate therefrom, in particular a mobile device (for example a metering device), which can preferably be introduced into the treatment room of the dishwasher ,

For example, the device performing the method is or comprises the

Household device, in particular the dishwasher. If the dishwasher itself is designed for this purpose, the method can be carried out with a small number of devices and in particular without an additional separate device for the user.

Alternatively, however, an additional and separate device is provided for the dishwasher. This has the advantage that the method can generally also be carried out independently of the type and properties of the dishwasher, which would otherwise not be possible or would not be possible to the same extent. The separate device is, for example, a mobile (portable) device. For example, the separate device is a mobile device, which can optionally have a communication connection with the dishwasher (for example, a wireless network).

However, the separate device can also be a mobile device which is introduced into the dishwasher in particular (for example during operation), that is to say is introduced into the interior or treatment room in the example of a dishwasher. Such a separate device is, for example, a metering device which is designed to dispense a substance (in particular a substance)

Dispense detergent) to the dishwasher. Such a separate device can be in communication-related connection with the dishwasher, a mobile device and / or a remote server (for example, in order to collect the information acquired (e.g.

Acceleration information) to be exchanged).

A housing surrounding the device is set up, for example, in the

Treatment room of the dishwasher to be positioned and in particular has a corresponding size, which allows the housing or the device at least partially bring in and / or remove the treatment room. In particular, the housing or the device can be positioned loosely and / or without connecting means in the treatment room.

For example, the housing or the device in the dishwasher is to be introduced and / or removed from the treatment room together with the objects to be cleaned. The housing of the device in particular partially or completely encloses individual or all means of the device. In particular, the housing is designed to be watertight so that individual or all means of the device do not come into contact with water when the device is in a treatment room, for example the treatment room of the dishwasher and

is positioned particularly during a treatment.

The device or the housing according to the second aspect is, in particular, a mobile and / or portable device and / or a device different from a dishwasher. A mobile and / or portable device should be understood to mean, for example, a device whose external dimensions are smaller than 30 cm × 30 cm × 30 cm, preferably smaller than 15 cm × 15 cm × 15 cm. A device that differs from a dishwasher is, for example, a device that has no functional connection with the dishwasher and / or does not represent a part that is permanently connected to the dishwasher. For example, a mobile and / or portable device that is different from the dishwasher should be understood to mean a device that has been inserted (e.g. inserted) by a user into the treatment room of the dishwasher for the duration of a treatment process (e.g. cleaning program). An example of such a mobile and / or portable device that is different from a dishwasher is a dosing device and / or sensor device that is placed in the treatment room before the start of the cleaning program.

The housing can have at least one dispensing module which is set up to dispense at least one preparation into the treatment room of the dishwasher and / or to trigger an dispensing. Dispensing a preparation, for example comprising cleaning agents, should be understood, for example, to mean that the preparation is dispensed to the surroundings of the dispensing module and / or a storage container for the preparation. Output takes place, for example, through the output module. Alternatively or additionally, the output can be effected by the output module, e.g. B. the dispensing module causes the preparation to be dispensed through the storage container. For example, the preparation is dispensed through an output opening of the dispensing module and / or the storage container to the surroundings of the dispensing module and / or the storage container.

The housing also has, for example, at least one sensor module which is set up for this, at least one for the condition of the treatment room of the dishwasher

to determine characteristic sensor information. Such sensor information can be, for example, at least one parameter of a conductivity (for example one in the Substance located in the treatment room such as water and / or a cleaning solution or liquor) and / or the temperature, for example the temperature in the treatment room and / or the temperature of a substance in the treatment room such as water and / or the brightness (e.g. whether light enters the treatment room of the dishwasher or does not act).

Correspondingly, the sensor module can comprise one or more sensors which are set up to record characteristic sensor information, for example a conductivity sensor and / or a temperature sensor (for example a thermocouple). A sensor is also to be understood to mean, for example, a mechanical sensor (e.g. a pressure sensor) and / or an optical sensor (e.g. a CCD sensor).

An acceleration sensor (also referred to as an accelerometer) is a sensor that measures its acceleration. This is done, for example, by determining the inertial force acting on a mass of the acceleration sensor. Thus, e.g. B. determine whether an increase or decrease in speed is taking place. Such one

Acceleration sensor can for example be comprised by the at least one sensor module.

An acceleration sensor can represent a motion sensor, for example. Such a motion sensor can detect a change in position, for example. For example, a movement can be detected by means of an acceleration sensor such that, for. B. Movements can be calculated as an integration via recorded information (e.g. measured values) of an acceleration sensor. For example, such a position determination of the device, for. B. in the

Treatment room can be carried out by the dishwasher.

The information detected by the acceleration sensor represents, for example

Acceleration and / or movement of the device according to the second aspect, which comprises the at least one acceleration sensor. Furthermore, for example, that of the

Acceleration sensor information, for example, represent a specific position and / or orientation of the at least one acceleration sensor within the dishwasher.

The at least one acceleration sensor detects the measured values representing the course, for example with a predefined sampling frequency, e.g. B. from 0.001 Hz to 1 GHz, preferably from 0.1 to 25 MHz.

To operate the at least one acceleration sensor with a power source, a supply voltage of approximately 1 V - 6 V, preferably approximately 2.5 V - 4.0 V, is required, depending on the type of acceleration sensor used. The acceleration sensor can be operated in particular with a supply voltage of 1.9 V to 3.6 V, so that an autonomous use, for. B. with a battery as an energy source. An acceleration sensor that also has a high temperature tolerance is particularly suitable. This includes in particular a faultless function of the acceleration sensor at high ambient temperatures (e.g. greater than 60 ° C - 65 ° C, 70 ° C - 75 ° C, 80 ° C - 85 ° C, 90 ° C - 95 ° C, or understood).

Furthermore, such an acceleration sensor has, for example, a sensitivity (resolution) which, for. B. is in the range of detectable accelerations of ± 8 g, ± 7 g, ± 6 g, ± 5 g, ± 4 g, ± 3 g, ± 2 g, ± 1 g or less. According to the invention, acceleration sensors with a detectable range of ± 2, ± 1 g or less are particularly suitable, in particular due to the occasionally small deflections or accelerations that are detected during the execution of the method according to the first aspect of the invention.

The at least one acceleration sensor has a resolution (also as

Sensitivity) per LSB (Least Significant Bit) from about 0.001 to about 1.0 milli g

(gravities) / LSB, preferably from about 0.05 to about 0.25 mg / LSB.

The resolution of milli g per LSB represents a factor (sensitivity) with which

Unprocessed measured values that are recorded by the at least one acceleration sensor are multiplied in order to be able to represent the resolution that the at least one acceleration sensor provides as a measured value. Such can, for example, with the at least one

Acceleration sensor an acceleration information can be determined, which represents an acceleration of 0 g to 1000 g, preferably from about 0.0001 g to about 16 g.

For example, a sensitivity (resolution) of the acceleration sensor by means of an analog-digital (A / D) converter, e.g. B. with a resolution of 16, 20, or 24 bits, of about 0.06 milli g can be achieved.

The at least one acceleration sensor has, for example, a sensitivity of about 0.001 mg / LSB (least significant bit) to 1.0 mg / LSB, preferably from about 0.05 mg / LSB to 0.25 mg / LSB.

The acceleration sensor is, for example, a MEMS (MicroElectroMechanical Systems) multi-axis acceleration sensor. Such a MEMS sensor typically measures one

Changing a capacity when changing an acceleration value.

The acceleration information determined by the acceleration sensor is, for example, at least partially indicative of a loading state of the dishwasher. The acceleration information determined by the acceleration sensor represents, for example, whether or not the treatment room is loaded by the dishwasher or to what degree Treatment room of the dishwasher is loaded. Additionally or alternatively, the acceleration information determined by the acceleration sensor can therefore be characteristic of how full (e.g. as a percentage of the maximum possible capacity) the treatment room is

Dishwasher is loaded (or filled). This can be done as part of determining the

Evaluation information can be determined based on the acceleration information.

As part of the determination of the evaluation information, it is determined whether one or more characteristic actions have been carried out by a user, and if applicable, storage of an action information representing the one or more actions, which includes the specific evaluation information or at least a part of the determined Evaluation information is.

The acceleration information is evaluated, for example, by the course of the

Acceleration values that are included or represented by the acceleration information are analyzed, e.g. B. on the presence of characteristic patterns with which, for example, at least a portion of the course can be compared. In this way, it can be concluded, for example, that the dishwasher is loaded. Further configurations with regard to the loading condition of the treatment room

Dishwasher are explained in more detail below.

Then there is an output or cause the output of the specific

Evaluation information. This can be done once, for example. Alternatively, by continuously capturing at least one piece of acceleration information and then determining the evaluation information (at least based on the part of the acceleration information that has been added and for which there is accordingly none yet

Evaluation information was determined). The output or the initiation of the output of the evaluation information can, for example, be carried out several times. The output can be given to the dishwasher, for example, in the event that the method according to the first aspect of the invention is separate from that of the dishwasher

Device is carried out. Alternatively or additionally, the dispensing or causing the dispensing can take place, for example, to a device which is different from the dishwasher or from the separate device, such as, for. B. a server. The server can provide so-called cloud services, for example, such a server can provide one

Determine control information for the device according to the second aspect of the invention, to name just one non-limiting example.

In one embodiment according to all aspects of the invention, the at least one

Acceleration information in relation to a predefined orientation and / or positioning of the at least one acceleration sensor in the treatment room of the dishwasher.

The orientation and / or the positioning of the acceleration sensor within the

Treatment room of the dishwasher are predefined. This is the case, for example, if the acceleration sensor does not change its orientation and / or positioning in relation to the treatment room of the dishwasher over the duration of the execution of the method according to the first aspect of the invention. For example, the device can further comprise means for orienting and / or positioning in relation to the treatment room

To be able to determine the dishwasher. Alternatively, for example, the device according to the second aspect, which is set up to carry out the method according to the first aspect, can comprise instructions (eg markings or the like, to name just one non-limiting example), so that, for example, a user can use the The device according to the second aspect of the invention can be introduced into the treatment room of the dishwasher in such a way that the orientation and / or positioning of the at least one acceleration sensor with respect to the treatment room of the dishwasher is predefined.

In one embodiment according to all aspects of the invention, the at least one evaluation information is determined while the at least one is being acquired

Acceleration information is continued.

The determination of the at least one evaluation information is carried out, for example, while the acquisition of the at least one acceleration information is continued. This means that, for example, initially for a predefined period of time, e.g. B. a minute to name just one non-limiting example, measured values using the at least one

Acceleration sensor are detected, or alternatively or additionally the detection of the

Acceleration information is started when, for example, a characteristic action of the user has been carried out, e.g. B. opening or closing the treatment room

closing door, just to name a non-limiting example. In addition, it can

Determine the evaluation information to be started or done. At the same time

For example, the acquisition of measured values by means of the acceleration sensor continues. This enables, in particular, e.g. B. loading or unloading the treatment room

Monitor the dishwasher successively.

In an alternative embodiment according to all aspects of the invention, the determination of the at least one evaluation information is carried out separately from the detection of the at least one acceleration information.

In this alternative, both events do not take place at the same time. In one embodiment according to all aspects of the invention, the method further comprises:

Determining control information based at least in part on the

Evaluation information, the control information causing a metering device (for example arranged in the treatment room of the dishwasher) to produce one according to the

Control information to perform defined dosing of cleaning and / or care products.

The dosing device is controlled and / or regulated based on the control information. The metering device can, for example, be an autonomous or built-in metering device. The

Dosing device can also be part of the device according to the second aspect of the invention, for example, or can be included in the device according to the second aspect of the invention. In this case, the device according to the second aspect of the invention and the dosing device form a single entity. The dosing device is alternatively a device separate from the device according to the second aspect of the invention.

The control information can furthermore operate or control an operation of the

Initiate or effect dishwasher at least taking into account the specific evaluation information. Such operation or control can consist, for example, in that a cleaning program of the dishwasher is selected or changed, that one or more process parameters are carried out by the dishwasher

Cleaning program are changed and / or that process sections are added or omitted.

According to a further embodiment of the method according to the first aspect, the control information also influences:

switching the dishwasher on and / or off;

selecting, compiling and / or dosing one for the

Detergents to be used in dishwashers; and or

a dishwasher cleaning program.

With regard to switching the dishwasher on and / or off, it can be influenced, for example, whether the dishwasher is switched on and / or off (at all) and / or at what time (time, date) the dishwasher is switched on and / or off to name just a few non-limiting examples.

Influencing the selection, compilation and / or dosing of one for the

Detergent to be used in the dishwasher can be carried out by different actions. For example, the amount to be metered (e.g. the amount of detergent and / or rinse aid), the time of metering, the product to be metered or individual ingredients or combinations thereof. A dosing device and / or an output module, which can be included in the device according to the second aspect of the invention, can carry out a corresponding dosing of the cleaning agent.

The control information can, for example, cause delivery and / or triggering of the output of a preparation on the part of an output module which, for. B. from the device according to the second aspect of the invention or can be connected thereto. For example, the control information was determined in such a way that, for example, a lot of cutlery and / or dishes and / or pots were loaded in the treatment room of the dishwasher, so that intensive cleaning can be carried out by means of a corresponding cleaning program in the dishwasher.

The cleaning program of the dishwasher can be influenced, for example, by selecting a specific (pre-programmed) program that

Additional programs are run through, that the program runtime is influenced (extended or shortened), that individual parameters of the program (for example the temperature, the drying time, to name just a few non-limiting examples) are changed.

In addition, it is possible that not only the operation or control of an operation of the

Dishwasher (automated) based on the control information, but that the user is also given a recommendation. For example, in addition to an automated adaptation of the dishwasher, it may also be possible for a recommendation to be displayed to the user, for example by means of an output device of a user interface (eg comprised by the dishwasher). For example, the user can be advised that e.g. B. by appropriate storage of used objects in the treatment room of the dishwasher tend to develop bad odors, so that based on the decision of the user, for example, this initiates the execution of a cleaning program. In this way, for example, the development of bad smells can be counteracted.

An embodiment according to all aspects of the invention provides that the device according to the second aspect is set up to communicate with the dishwasher, in particular to communicate wirelessly with the dishwasher.

For example, communication with the dishwasher can take place by means of a communication interface included in the device according to the second aspect of the invention. The communication interface is in particular designed to be wireless with the

Communicate dishwasher. An embodiment according to all aspects of the invention provides that one or more characteristic actions of the user are represented by one or more of the following actions i) to iv):

i) loading or unloading an object into the treatment room of the dishwasher; ii) pulling out or pushing in a basket of the treatment room of the dishwasher; iii) Opening or closing the treatment room of the dishwasher

locking door;

iv) Rinse cycle of a cleaning program that can be carried out by the dishwasher.

Actions i) to iv) are combined, for example. For example, you can start with a

Object are brought into the treatment room of the dishwasher, for which it was previously necessary to pull out a basket of the dishwasher. If the treatment room was not locked by the door, action iii) was first carried out by the user, and again after the insertion of the object in the form of a closing of the door.

Each of the actions i) to iv) can be determined based on the acceleration information as part of the determination of the evaluation information, since each of the actions i) to iv) is represented by characteristic patterns in the acceleration information or the course of the measured values represented by the acceleration information is.

In a further embodiment according to all aspects of the invention, the acceleration information is at least partially indicative of a movement of the at least one acceleration sensor with respect to its orientation and / or positioning in the treatment room

Dishwasher.

A movement of the at least one acceleration sensor is characterized, for example, by a movement of the at least one acceleration sensor comprising one or more degrees of freedom, by a movement path, or a combination thereof. For example, a distance covered by the at least one acceleration sensor can be represented on the basis of the one or more degrees of freedom and / or the movement path. For example, the further the distance traveled, the more likely it is that e.g. B. a basket of the dishwasher has been inserted or removed (action ii) by the user).

In the event that a vibration was detected as a movement of the at least one acceleration sensor in the course represented by the acceleration information, depending on the strength of the vibration and / or the duration of the decay of the vibration caused by the vibration, the the at least one acceleration sensor has been moved, e.g. B. Action i) or iii) of the user. In the event that a slight but persistent vibration was detected as movement of the at least one acceleration sensor in the course represented by the acceleration information, action iv) can be present, for example, in which the user e.g. B. has initiated a cleaning program by the dishwasher.

An embodiment according to all aspects of the invention provides that the object that is brought into or removed from the treatment room of the dishwasher is at least a piece of cutlery or a piece of crockery.

Depending on the course, which is represented by the measured values of the acceleration information, and / or the ratio of the amplitude and / or the ratio of the frequency of the change in the amplitudes of the measured values, which are represented by the acceleration information, the evaluation information can be determined in such a way that this represents whether z. B. dishes, cutlery and / or pans or pots were introduced into or removed from the treatment room of the dishwasher.

In one embodiment according to all aspects of the invention, the method further comprises:

Acquiring or receiving one or more sensor information, the one or more sensor information being indicative of a temperature or a brightness (e.g.

Light intensity), the evaluation information also being determined based at least in part on the one or more sensor information items.

Actions i) to iv) are combined, for example, with sensor information that represents a temperature and / or brightness or light intensity. In particular, the sensor information can be determined to verify the acceleration information, at least in part

Evaluation information can be used. For example, the washing cycle of a cleaning program that can be carried out by the dishwasher can be verified using temperature information that is represented by the sensor information. Furthermore, for example, with brightness information represented by the sensor information, the opening or closing of a door closing the treatment room of the dishwasher can be verified, to name just a few non-limiting examples.

For example, at least one temperature sensor can be used to record sensor information indicative of a temperature. For example, at least one brightness sensor or light intensity sensor can be used to detect sensor information indicative of a brightness. An embodiment according to all aspects of the invention provides that the

Acceleration information and / or the one or more sensor information are recorded over a predefined period of time.

The predefined time period is indicative of a continuous or discrete acquisition of the acceleration information and / or of one or more sensor information. The

predefined time period can be defined, for example, by a certain time period, e.g. B. for a period of a few minutes, up to several days or weeks, to name just a few non-limiting examples. The detection of the acceleration information and / or the one or more sensor information can trigger the detection for a period of time to be determined or predetermined. For example, if the opening of the dishwasher door has been determined (action iii)), the acceleration information and / or the one or more sensor information can be recorded for a period of 1 to 10, 2 to 8, 3 to 7, 4 to 6 or 5 minutes take place, since it can be assumed, for example, that loading or unloading of objects takes place after opening the door. In the same way, for example, closing the door can stop the detection of the acceleration information and / or the one or more sensor information, since it can be assumed that the user has finished loading or unloading objects. It goes without saying that further scenarios are possible in the manner of the above examples.

An embodiment according to all aspects of the invention provides that the at least one

Acceleration sensor is arranged within the treatment room of the dishwasher, in particular on or in a lower basket for receiving objects to be cleaned, so that the predefined positioning of the at least one acceleration sensor within the

Treatment room of the dishwasher is present.

Accordingly, the acceleration information then recorded represents a movement and / or acceleration of the at least one acceleration sensor in relation to the lower basket.

If the acceleration information represents a strong vibration, for example, the evaluation information can be determined taking into account that with high

Probability there has been a vibration of the basket of the dishwasher in or on which the at least one acceleration sensor is arranged. If, on the other hand, the vibration determined within the scope of the evaluation information is less pronounced, the probability is high that objects have occurred in a basket that deviates from the basket in or on which the at least one acceleration sensor is arranged.

The evaluation information is determined, for example, as a function of a predefined orientation and / or positioning of the at least one acceleration sensor. By knowing the orientation, it can be analyzed, for example, when determining the evaluation information, whether a dishwasher basket has been inserted or removed, and / or whether objects have been loaded into or removed from the treatment room (e.g. in the direction of movement of the first one) Impulse with which the at least one acceleration sensor was set in motion is taken into account accordingly, to name just one non-limiting example).

Acceleration information represents a signal in the direction of each of two or three degrees of freedom.

The at least one acceleration information is detected, for example, by the at least one acceleration sensor, for example in the direction of 2-axes (x-y-axes) or 3-axes (x-y-z-axes) in relation to a Cartesian coordinate system. The respective axes are perpendicular to each other so that two or three (all) spatial directions can be recorded.

Furthermore, the detected acceleration information can represent, for example, whether the acceleration is positive or negative.

An embodiment according to all aspects of the invention provides that the determination of the

Evaluation information for every two or three degrees of freedom is carried out separately.

The respective measured values of the acceleration information (eg as measured signals) in one of the two or three directions of the acceleration information can be compared with one another, for example, in the context of determining the evaluation information. Alternatively or additionally, the evaluation information can be determined for each signal in one of the two or three

Degrees of freedom or in the corresponding direction.

If the at least one acceleration information represents a signal in the direction of each of three degrees of freedom, the individual measured values of each direction can be compared with one another, for example. In this way it is possible, for example, that at least one of the z. B. recognized characteristic pattern, which is represented by acceleration information in one direction (e.g. x-direction or along the x-axis of the coordinate system), with a signal in a further direction (e.g. y-, or z-direction, or along the y- or z-axis of the

Coordinate system) to verify the characteristic pattern that is part of the

Determining the evaluation information was recognized, is compared.

For example, all the results of the evaluation information in the event that there is evaluation information for each of the two or three degrees of freedom, which is a movement and / or Represent acceleration direction of the at least one acceleration sensor, are compared with each other or with each other. In this way, the results can be verified against each other, for example. This enables, for example, the detection of measurement errors, which are identified by the verification and then cannot be taken into account, for example, when determining the evaluation information.

An embodiment according to all aspects of the invention provides that the particular

Evaluation information is indicative of a washing cycle, and / or loading or unloading of a basket arranged within the treatment room of the dishwasher or a level within the treatment room of the dishwasher, in which objects to be cleaned can be arranged, and / or for a size of one in an inside the Treatment room of the dishwasher arranged basket or arranged level brought in or removed object. In this way, the evaluation information is also indicative of a loading state of the treatment room of the dishwasher.

It is not only possible to determine based on the at least one

Acceleration information as to whether (at all) objects are in the treatment room of the

Dishwasher were introduced or removed from it, but also to be able to determine based on the at least one acceleration information, such as. B. loading with z. B. Objects have been made. For example, loading and / or unloading with large

Objects are distinguished from loading and / or unloading with smaller objects. Furthermore, it can be distinguished whether large or small objects such. B. in an upper, middle and / or lower located in the treatment room of the dishwasher or a corresponding upper, middle, and / or lower level.

Furthermore, it can be determined how many items, optionally dedicated according to the size of the

Item (e.g. cutlery, small, medium, large pot, to name just a few non-limiting examples) and the position of the removal or insertion (e.g. basket or level) was loaded or unloaded. This can be done, for example, based on the intensity (amplitude, frequency, change in amplitude, or the like) of the at least one acceleration information

represented measured values (or signals) on the respective axes (e.g. in the direction of one, two or three degrees of freedom) of the at least one acceleration sensor (within the scope of determining the evaluation information). For example, it can be determined which basket (level) was moved. Also z. B. can be determined whether in the upper basket, in the middle and / or in the lower basket were loaded or unloaded. Furthermore, it is consequently possible to determine whether the cutlery and / or crockery and / or cookware (e.g. pots, pans, lids for pots and / or pans) have been cleared or cleared, and also how many parts and cleared or cleared out were. In addition, their size can also be determined. An embodiment according to all aspects of the invention provides that the determination of the

Evaluation information is also based at least in part on a nominal capacity of the treatment room of the dishwasher.

Knowing the nominal capacity of the dishwasher (e.g. 13 place settings, or cubic meters of space (volume), to name just a few non-limiting examples) B. can be determined at any time by determining the evaluation information, for. B. how fully loaded the dishwasher. This can be represented, for example, by correspondingly determined loading information. The loading information can be determined, for example, as part of the determination of the evaluation information. The loading information can, for example, be included in the evaluation information then determined, or at least part of the evaluation information represents the loading information.

Based on the loading information, a loading protocol can be generated, for example, that e.g. B. indicative of the type and / or number of objects in the individual baskets (or level, also referred to as segments) that are currently arranged or were arranged historically. The loading information can be taken into account, for example, when determining the control information in such a way that the determination of the control information is also based on the

Loading information is provided. The control information determined in this way can then

For example, cause the dishwasher to be used or used

Dosage of detergent or preparation depending on the actual load (i.e. type, number, quantity of objects), to name just one non-limiting example.

Evaluation information further includes:

Determining a time behavior of a vibration based at least in part on the at least one acceleration information, the vibration being represented by the course of the measured acceleration values on the part of the acceleration information, the time behavior being indicative of a quantity of one in the treatment room

Is in or out of the dishwasher.

The course of measured acceleration values by the at least one

Acceleration information is represented, is consequently at least in parts or sections characteristic of the time behavior of at least one vibration. It goes without saying that since the at least one acceleration information item was recorded over a predefined period of time, that different time periods depend on the measured values of the at least one

Acceleration information are represented, each of which can represent different vibrations (sometimes overlapping one another). An example is the unloading of objects from the treatment room

Dishwasher listed (e.g. represented by the characteristic action i) of the user). With sufficient resolution of the measured values of the at least one acceleration information item (e.g. resolution with approximately 100 Hz), it can be determined that these signals measured by the acceleration sensor can be broken down into individual steps, that is to say individual items of crockery and cutlery. Each of these steps, that is to say one step corresponds, for example, to the unloading of exactly one object from the treatment room of the dishwasher, can be found as a freely damped oscillation in its complete dimensions in the course of the acceleration information.

For example, the size of a pot or the size of an object that has been introduced into or removed from the treatment room by a user can be determined via the respective freely damped vibration, to name just one non-limiting example.

For objects in the form of pots and lids, for example, to name just a few non-limiting examples, this is possible in such a way that the size of the pot or the object can be inferred from the time behavior of the vibration. The longer z. B. the vibration lasts, and z. B. the more it oscillates, the larger the object with which the treatment room of the dishwasher has been loaded or unloaded. Furthermore, the oscillation duration and the intensity of the oscillation correlate with the mass of the corresponding one or the special objects of a pot or pots

Object. In this way, for example, the size of the loaded or unloaded object can be determined.

In a further exemplary embodiment according to all aspects of the invention, the evaluation information is determined by means of an artificial neural network.

For example, the at least one acceleration information and optionally the one or more sensor information can be communicated (for example transmitted) to a server which comprises or is connected to an artificial neural network. Determining the

Evaluation information can then be carried out, for example, using the artificial neural network. Then, for example, the result can be communicated to the device according to the second aspect of the invention and / or the dishwasher.

The artificial neural network can also be designed, for example, in the manner of a so-called generative adversarial network (GAN; in German: opposing generating networks). Such a GAN comprises, for example, at least two artificial neural networks which compete against one another in such a way that their results are compared with one another. So can on the Quality of the result determined by the artificial neural network. For example, a first artificial neural network of the GAN works with data that it e.g. B. from the ongoing measurements (for example acquiring at least one acceleration information and optionally acquiring at least one sensor information) receives and generates a statement (for example by means of a corresponding generator) about the result. In the present case, the status information is thus determined, for example. The GAN's second artificial neural network (also referred to as a discriminator) can, for example, now compare this statement with an ideal, predetermined result or an ideal trained result. If the second artificial neural network determines no or only a slight difference to the statement of the first artificial neural network, an optimal result is achieved, for example. In this way, the determination of the status information can be significantly improved by means of such an artificial neural network designed as a GAN.

The artificial neural network includes, for example, an evaluation algorithm, so that, for example, examples can be learned from training cases and these can be generalized as a basis after the end of the learning phase in order to determine a result (the evaluation information). This means that examples are not simply memorized, but patterns and regularities are recognized in the learning data. Different approaches can be followed. For example, supervised learning, partially supervised learning, unsupervised learning, strengthened learning and / or active learning can be used. Supervised learning can take place, for example, using an artificial neural network (for example a recurrent neural network) or using a support vector machine. Unsupervised learning can also be carried out, for example, using an artificial neural network

(for example an auto encoder). Accelerated information and optional sensor information and / or the evaluation information determined after a run, for example, of the artificial neural network are then used in particular as learning data.

It is also possible to use the repeated acquisition of the acceleration information and the optional one or more sensor information or the evaluation information for machine learning. For example, a user profile or one or more pieces of information included in the user profile can be determined, for example, at least in part based on machine learning.

By means of these measures, the reliability of the monitoring of the loading or unloading of the treatment room of the dishwasher, and / or a control and / or regulation of the device according to the second aspect of the invention and / or the dishwasher, and consequently in particular the treatment of those to be cleaned Objects by the Dishwasher, especially for improved removal of contaminants, can be increased.

Each of the training cases can, for example, by an input vector, a

Acceleration information and optionally one or more sensor information and an output vector of the artificial neural network can be given.

Each training case of the training cases can be created, for example, by adding to the

Training case associated control and / or regulation of the device according to the second aspect of the invention and / or the dishwasher, and determining the corresponding

Evaluation information in a predetermined state (e.g. defined quantity, type and position within the treatment room of the dishwasher of one or more

Objects) is transferred, and representative of acceleration information characteristic of the condition of the treatment room and optionally one or more sensor information is acquired, and at the same time a z. B. manual analysis of the state of the

Treatment room of the dishwasher is carried out. The then captured

Acceleration information and optionally the one or more sensor information are determined, for example, as an input vector, and the (actual) state of the treatment room of the dishwasher is determined as an output vector of the training case as reference evaluation information. The evaluation information determined by the artificial neural network is then transferred to that of the output vector. In this way, the artificial neural network can be taught iteratively or successively and the accuracy (e.g. hit rate) of the artificial neural network can be increased.

Detailed description of some exemplary embodiments of the invention

1 first shows a schematic illustration of an exemplary embodiment of a system 1 according to the invention comprising the devices 200, 300 and 400. The system 1 is used for

Execution of exemplary methods according to the invention. The device 200 is an exemplary mobile device 200, which in this case can be introduced into the treatment room of the dishwasher 300. Both the device 200 and the dishwasher 300 can each be a device according to the invention. Furthermore, the system 1 comprises the mobile device 400 in the form of a smartphone as a further device. The mobile device 400 can also carry out individual steps of exemplary methods according to the invention. However, device 400 may also be a computer, a desktop computer, or a portable computer, such as a laptop computer, a tablet computer, a personal digital assistant (PDA), or a wearable. In addition or as an alternative to devices 300 and 400, the system may also include a server (not shown). It is also conceivable that the system 1 also comprises fewer or more than three devices.

Each of the devices 200, 300, 400 may have a communication interface to communicate with one or more of the other devices or information

exchange.

FIG. 3 shows a flow diagram 30 of an exemplary embodiment of a method according to the first aspect of the invention. The flowchart 30 can be, for example, from the device 200 according to FIG.

1 run. The flow diagram 30 can be carried out, for example, by the device 300 according to FIG. 1. The flow diagram 30 can, for example, be carried out together both by the device 200 according to FIG. 1 and by the device 30 according to FIG. 1. The flow diagram 30 can be carried out together by the devices 200, 300 and 400 according to FIG. 1, for example. In a first step 301, at least one acceleration information item is recorded. The detection takes place, for example, by means of an acceleration sensor (e.g.

Acceleration sensor (s) 215 according to FIG. 2), which is correspondingly encompassed by the device 200 or 300 according to FIG. 1. The acceleration sensor is in the during the detection

Treatment room of the dishwasher 300 arranged. In the event that the device 200 according to FIG. 1 comprises the acceleration sensor, it is at least temporarily arranged during the detection within the treatment room of the dishwasher 300.

In an optional second step, one or more sensor information items are recorded or received. The one or more sensor information items are acquired, for example, by a temperature and / or brightness sensor (e.g. sensor (s) 216 according to FIG. 2). In the event that the one or more sensor information is obtained, this is initially detected, for example, by the device 200 and / or 300 according to FIG. B. Device 400 of FIG. 1 transmitted, for. B. by means of a

Communication interface. In the latter case, the following step 303 is carried out, for example, by the device 400 according to FIG. 1.

In a third step 303, at least one piece of evaluation information is determined. As part of this step 303, a time behavior of an oscillation 303-1 can optionally be determined based on the at least one acceleration information recorded in step 301. In step 303, a determination is made as to whether one or more characteristic actions have been carried out by a user (step 303-2). In step 303, action information representing the one or more actions of step 303-2 is stored (step 303-3). All of the steps included in step 303 can be carried out by one of the devices 200, 300 and 400 according to FIG. 1. Alternatively, at least one of all steps 303, 303-1, 303-2, and 303-3 can be carried out by a different device, which therefore does not carry out the rest of steps 303, 303-1, 303-2, and 303-3 become.

In a fourth step 304, the evaluation information determined in step 303 is output or caused to be output. For example, the evaluation information is output to a device 200, 300 or 400 according to FIG. 1. In the event that

If evaluation information is output, for example, to the dishwasher 300, the dishwasher 300 can, for example, carry out cleaning of objects based on the evaluation information, to name just one example. In the event that

If evaluation information is output, for example, to the device 400 according to FIG. 1 (eg a user's mobile device), the user of the device 400 can monitor the loading or unloading of the dishwasher 300 using his mobile device 400. In an optional fifth step 305, control information is determined based on the evaluation information or on the output evaluation information. This specific control information can in turn be output. In the event that

1, or was determined by the device 400 according to FIG. 1, this device 400 can also execute the step 305. The specific control information can then be output, for example, by the device 400 to the device 200 and / or 300 according to FIG. 1, so that the device 200 and / or 300 according to FIG. 1 can trigger an action corresponding to the control information, e.g. B. Perform a dosing or start a cleaning program, to name just a few non-limiting examples.

The step of acquiring the acceleration information 301 and / or the step 302 of acquiring or obtaining one or more sensor information can be carried out simultaneously with the step 303. This means that, for example, after step 301 and optionally step 302 have been carried out for the first time, step 303 of determining the

Evaluation information is carried out while the step 301 and optionally the step 302 are carried out further by detecting further acceleration information (step 301) and optionally further sensor information (step 302).

2 now shows a block diagram 20 of an exemplary embodiment of a device according to the second aspect of the invention for carrying out an exemplary embodiment of a method according to the first aspect of the invention. The block diagram 20 from FIG. 2 can be an example of the device 200 shown in FIG. 1, the dishwasher 300 shown or the mobile device 400 shown (or a part thereof).

Processor 210 of device 20 is in particular a microprocessor, microcontroller,

Microcontroller, digital signal processor (DSP), application-specific integrated circuit (ASIC) or field programmable gate array (FPGA).

Processor 210 executes program instructions stored in program memory 212 and, for example, stores intermediate results or the like in working or main memory 211. For example, program memory 212 is a non-volatile memory such as flash memory

Magnetic memory, an EEPROM memory (electrically erasable programmable read-only memory) and / or an optical memory. Main memory 21 1 is, for example, a volatile or non-volatile memory, in particular a random access memory (RAM) such as a static RAM memory (SRAM), a dynamic RAM memory (DRAM), a ferroelectric RAM memory (FeRAM) ) and / or a magnetic RAM memory (MRAM). Program memory 212 is preferably a local one permanently connected to device 20

Disk. Data carriers which are permanently connected to the device 20 are, for example, hard disks which are built into the device 20. Alternatively, the data carrier can, for example, also be a data carrier which can be connected to the device 20 in a separable manner.

Program memory 212 contains, for example, the operating system from device 20, which is loaded at least partially into main memory 211 when device 20 is started and is executed by processor 210. In particular, when device 20 is started, at least part of the kernel of the operating system is loaded into main memory 211 and executed by processor 210.

The operating system in particular enables the device 20 to be used for

Data processing. For example, it manages resources such as main memory 211 and

Program memory 212, communication interface 213, the optional input and output device 214, provides basic functions to other programs, among other things, through programming interfaces, and controls the execution of programs.

Processor 210 also controls communication interface 213, which can be, for example, a network interface and can be designed as a network card, network module and / or modem. The communication interface 213 is in particular set up to connect the device 20 to other devices (for example at least one of the devices 200, 300 and / or 400 according to FIG. 1), in particular via a (wireless) communication system, for example a network to manufacture and communicate with them. The communication interface 213 can, for example, receive data (via the communication system) and forward it to processor 210 and / or receive data from processor 210 and send it (via the communication system). Examples of a communication system are a local area network (LAN), a large area network (WAN), a wireless network (for example according to the IEEE-802.11 standard, the Bluetooth (LE) standard and / or the NFC standard), a wired Network, a

Cellular network, a telephone network and / or the Internet. For example, the communication interface 213 can be used to communicate with the Internet and / or other devices. In the case of devices 200, 300, 400 according to FIG. 1, the respective

Communication interface 213 can for example be communicated with the respective other devices 200, 300, 400 or the Internet.

Via such a communication interface 213, one or more optional sensor information (cf. step 302 according to FIG. 3) and / or evaluation information (cf. step 303 or 304 according to FIG. 3) can in particular be received (received) or sent to it another device will be issued. In addition, processor 210 can control at least one optional input / output device 213. Input / output device 213 is, for example, a keyboard, a mouse, a display unit, a microphone, a touch-sensitive display unit, a loudspeaker, a reader, a drive and / or a camera. Input / output device 213 can, for example, receive input from a user and forward it to processor 210 and / or receive and output information for the user from processor 210.

Finally, the device 20 can also comprise further components 215, 216.

For example, acceleration sensor (s) 215 may include one or more

Sensor (s) 216 are, for example, a temperature sensor to record temperature information and / or a brightness sensor to record brightness information. Both the temperature information and the brightness information can be one or more

Sensor information may be represented (see step 302 of FIG. 3).

The exemplary embodiments listed below should also be understood as disclosed:

The exemplary embodiments listed are able to load and unload in

Identify automatic dishwashers and differentiate them from rinsing processes.

It is advantageous to determine how often a user uses a dishwasher (e.g.

Dishwasher 300 of FIG. 1) loaded with dishes and cutlery before he turns them on.

It is advantageous to determine in which baskets the user of a dishwasher loads dishes and cutlery.

It is also advantageous to determine what type of dishes the user is loading the dishwasher with.

It is also advantageous to determine when the user loads what type of dishes or cutlery into the dishwasher.

It is advantageous to determine when and how the user unloads the dishwasher.

From the type of loading, it is advantageous to create an instruction for a metering device (eg device 200 according to FIG. 1). It is advantageous to create and communicate a loading report.

These advantages can be achieved, for example, by using an acceleration sensor in the interior (treatment room) of a household or commercial dishwasher (generally referred to as a dishwasher in the sense of this description). On

Acceleration sensor, for example mounted on an electronic board of a self-sufficient

Dispenser, is able to fully record the vibrations, shocks and mechanical events that occur independently and at different times from a dishwashing process and make them accessible for interpretation. In combination with other sensors, e.g. B. a temperature sensor or a brightness sensor, the processes can be clearly described. The ascertained data can be fed to applications for machine learning, with which, for example, pattern analyzes are then created and these are then converted into algorithms for controlling a dosing device.

Embodiment A:

In a dishwasher, for example, an autonomous, automatic measuring and metering device (e.g. device 200 according to FIG. 1) according to the second aspect of the invention, comprising at least one acceleration sensor, e.g. B. arranged in the lower basket between dishes. The

For example, the dishwasher is fully loaded and has completed a rinse cycle. A user clears the dishwasher in a subsequent step.

Surprisingly, the unloading process carried out by the user can

Dishwasher can be evaluated, as the determined series of measurements according to FIGS. 4 to 7 show.

FIG. 4 shows a first exemplary course of measured acceleration values represented by the acceleration information 415 shown. Within the scope of determining the

Evaluation information can different actions (of the user) in the

Acceleration information 415 are determined, in the present case unlocking or opening a door, putting the door on (fully open), pulling out a lower basket, removing dishes from the lower basket, inserting the lower basket, and closing the door.

FIG. 5 shows a second exemplary course of measured acceleration values represented by the acceleration information 515 shown. Various actions (of the user) can be carried out in the context of determining the evaluation information

Acceleration information 515 are determined, in the present case unlocking or opening a door, fitting the door, pulling out an upper basket, removing dishes from the upper basket, pushing the upper basket in, and closing the door. FIG. 6 shows a third exemplary course of measured acceleration values represented by the acceleration information 615 shown. Within the scope of determining the

Evaluation information can different actions (of the user) in the

Acceleration information 615 are determined, in the present case unlocking or opening a door, putting the door on, pulling out a cutlery drawer, removing cutlery, it being possible to clearly differentiate between individual removal of cutlery and bundle removal of cutlery, insertion the cutlery drawer and closing the door.

7 shows a fourth exemplary course of measured acceleration values

represented by the acceleration information 715 shown. Within the scope of determining the evaluation information, various actions (of the user) can be carried out in the

Acceleration information 715 are determined, in the present case a removal of dishes from the lower basket. The decay of a freely damped oscillation, which was stimulated by the removal of dishes, is represented schematically by the amplitude envelopes.

As can be seen from FIGS. 4 to 7, the following actions of a user can be determined, for example, based on at least one acceleration information that was recorded according to a method according to the first aspect of the invention:

All mechanical processes during opening and closing and loading and unloading are clearly from the background noise of the acceleration sensor to the rest position

differ.

All mechanical processes during opening and closing and loading and unloading can be clearly distinguished from an ongoing flushing process.

The opening of the door must be clearly identified. It is a combination of unlocking, opening and putting on the door.

The pulling out of the individual baskets must be clearly identified. The intensity of the signal (oscillation) can be used to determine which basket (lower basket (also known as the lower basket), upper basket (also known as the middle basket), optional cutlery drawer (also known as the upper basket)) is being moved.

The removal of individual crockery and cutlery is visible and can be displayed on all basket levels.

Inserting the baskets and closing the door are clear and unambiguous

identify.

It is essential to recognize that the processes involved in unloading can be identified, but it is particularly important for the dosing device to determine that the machine is not loading, but rather that the machine is loading. Furthermore, the signal behavior in the lower basket differs from that of other baskets which are arranged in the treatment room of the dishwasher. Since the measuring and dosing device including the acceleration sensor is also located in the lower basket in the present case, so that its positioning and / or orientation is clearly defined within the treatment room of the dishwasher, the sensitivity to mechanical processes is increased once again. When taking a closer look at the unloading processes, they must be described as freely damped vibrations, especially in the vicinity of the measuring and dosing device.

The discharge process can be broken down into individual steps, i.e. individual crockery and cutlery parts, with good sensitivity (resolution in the present case approximately 100 Hz) of the signal (or measured value; represented by the at least one acceleration information) measured by the acceleration sensor. Every single process can be described in its complete dimension with the mathematics of a free damped vibration. In Fig. 7, for example, the amplitude envelope is shown as an external limitation. The successive amplitudes can clearly be seen in the decay curve. This is a mathematical description of the processes according to known rules of vibration theory in all parameters (e.g. decay coefficient,

Amplitude ratio, decay time, damping, damping constant, to name just a few non-limiting examples) possible.

Without being bound by theory, it is possible to evaluate these parameters over a large number of data sets, e.g. B. with the help of an (artificial) neural network, even possible to determine the nature of the dishes, e.g. Steel, porcelain, plastic or glass.

In contrast to the removal of dishes, which in most cases can be described as a process carried out continuously by the user, the loading takes place discontinuously in short time segments before a new wash cycle in the dishwasher. The loading period can be as long as you like, but is usually a period of 1 to 3 days (for example, due to the development of odors from cutlery and dishes that are used within the

Treatment room of the dishwasher). Often, only a few are

Dishes, such as B. put pots in the dishwasher.

Embodiment B:

Embodiment B shows an example of loading processes and their measurement-technical detection by means of an acceleration sensor. In a dishwasher, for example, is a self-sufficient, automatic measuring and dosing device according to the second aspect of the invention, comprising at least one acceleration sensor, e.g. B. arranged in the lower basket between dishes. For example, the dishwasher is empty.

In a subsequent work step, a user places various dishes in the dishwasher. Surprisingly, based on at least one

Acceleration information, which was determined by an acceleration sensor included in the dosing device, all individual steps of the loading of the

Treatment room of the dishwasher can be identified. 8 and 9 each show exemplary acceleration information.

8 shows a fifth exemplary course of measured acceleration values represented by the acceleration information 815 shown. Various actions (of the user) can be carried out in the context of determining the evaluation information

Acceleration information 815 are determined, in the present case opening the door (door open) and pulling out a lower basket, placing seven individual and large plates, placing seven individual deep-drawn plates, placing eight individual and small plates, placing a small saucepan, putting in a big saucepan, putting in a small pan, putting in a small sieve, and then pushing in the lower basket and closing the door.

FIG. 9 shows a sixth exemplary course of measured acceleration values represented by the acceleration information 915 shown. The acceleration information 915 of FIG. 9 represents that of FIG. 8, the acceleration information 915, in contrast to the acceleration information 815, being recorded with a higher resolution.

FIG. 8 shows the complete loading process of a lower basket on the y-axis of the acceleration sensor arranged by the dishwasher in the treatment room. X-axis and Z-axis (see Fig. 9) show a comparable picture.

Surprisingly, it is not only possible to observe the individual steps, but also the individual steps such. B. breaking down large plates into sub-steps, ultimately counting, e.g. B. how many items are or have been placed in the dishwasher. If you know the nominal capacity of the dishwasher (e.g. 13 place settings), you can determine at any time how fully loaded the dishwasher is. This is valuable information that e.g. B. can be used to control a self-sufficient or built-in metering device, provided the amount of dirt correlates with the load. Just as with unloading, the loading of an upper basket arranged inside the treatment room by the dishwasher can also be observed. The above, surprisingly, also applies to the upper basket. The intensity of the signals on the respective axes of the acceleration sensor can be used to determine which basket (plane) is being moved. It can also be determined in the upper basket, which dishes are placed and how much dishes are placed. In the example according to FIG. 10, the signal evaluation can be seen on the y-axis of the sensor. The X-axis and Z-axis show a comparable picture. Nevertheless, it can be advantageous to evaluate the signal (represented by the at least one acceleration information) on all axes, in particular when the actual number of dishes is to be determined, because the resolution of the signals on the axes can be of different accuracy.

Working example C:

In a dishwasher, for example, is a self-sufficient, automatic measuring and dosing device according to the second aspect of the invention, comprising at least one acceleration sensor, e.g. B. arranged in the lower basket between dishes. For example, the dishwasher is empty.

10 shows a seventh exemplary course of measured acceleration values represented by the acceleration information 1015 shown. Various actions (of the user) can be carried out in the context of determining the evaluation information

Acceleration information 1015 are determined, in the present case opening the door (door open) and pulling out the upper basket, the three consecutive placement of two tea cups, the placement of three small glass bowls, the placement of three saucers, the placement of six glasses, the Put six coffee cups, one lasagne bowl, one glass bowl, three plastic bowls, then push the upper basket in and close the door.

Fig. 1 1 shows an eighth exemplary course of measured acceleration values represented by the acceleration information 1 15 shown. In the context of determining the evaluation information, various actions (of the user) in the

Acceleration information 1 1 15 can be determined, in this case opening the door (door open) and pulling out the lower basket, placing a small lid and then placing a small pot, placing a medium-sized lid and then placing a medium-sized pot , putting in a large pot, then pushing in the lower basket and closing the door.

In a subsequent step, the user places various pots with matching lids in the lower basket of the dishwasher. Surprisingly, it is by means of one

Acceleration sensor recorded acceleration information possible, the individual steps of the Watching loading and recognizing the pots according to their size. Fig. 11 shows the loading of the lower basket with three different pots, which differ significantly in size.

Small pot: diameter 16 cm; Weight: 0.47 kg;

Middle pot: diameter 20 cm; Weight: 1.0 kg;

Large pot: diameter 24 cm; Weight: 1.8 kg.

11 schematically shows determined acceleration information from one

Acceleration sensor. Individual sections of the determined can be characteristic

Acceleration information for loading the dishwasher. It can be clearly seen in FIG. 9, for example, how objects are placed in the basket of the treatment room of the dishwasher. For example, there is also a surprising effect with pots and lids: the time behavior of the oscillation allows conclusions to be drawn about the size of the pot or the object. The longer the vibration lasts and the more it oscillates, the larger the object with which the treatment room is

Dishwasher was loaded. Furthermore, the oscillation duration and the intensity of the oscillation correlate with the mass of the corresponding pot in the special object or the special objects of a pot or several pots.

The information about the size of the loaded object can now be translated into instructions for the associated dosing device. For example, from the

In the presence of many large objects, a dosing mode or cleaning cycle can be activated, which is advantageous for cleaning these objects, e.g. B. an increase in detergent and / or rinse aid dosage, to name just one non-limiting example.

Overall, the creation of a loading protocol with z. B. the type and number of

Objects in the individual segments of the dishwasher are used to match the amount of cleaning and / or care agent to be dosed (e.g. detergent and rinse aid) to the number of objects to be cleaned with the aim of performance and

Use of chemicals with optimal results. The method according to the invention can be used in all known dishwashers - that is to say both in (private) households

Dishwashers as well as commercial dishwashers, e.g. B. continuously working dishwashers, the z. B. based on the method according to the first aspect of the invention can be controlled and / or regulated - so that it is possible to achieve an optimal use of cleaning and / or care products regardless of the size of the dishwasher. The method according to all aspects of the present invention can, for example, be carried out continuously, so that e.g. B. constantly one or more acceleration information (z. B. as corresponding data) by means of the acceleration sensor and then (successively) evaluated. In principle, one or more of the following aspects apply to all aspects of the invention:

All data can be saved locally and locally;

All data can be subjected to an additional data analysis;

All data can be processed with a machine learning tool;

Conclusions about user behavior can be drawn from the data;

User profiles can be created from the data; and

Algorithms can be derived from the results of data analysis and / or machine learning
